Answer:The price for renting a car at a car rental company is according to the following schedule: Write a MATLAB program in a script file that calculates the cost of renting a car based on the shown price schedule. The program must ask the user to enter the type of car (Sedan or SUV), the number of days, and the number of miles driven. The program then displays the cost (rounded to cents) for the rent in a sentence that reads: "The cost of the rent is XXX $." where XXX is the cost value in $. Run the program three times for the following cases: Sedan, 10 days, 769 miles. SUV, 32 days, 4, 056 miles. Sedan, 3 days, 511 miles. Use fprintf () to display the text and data. The data should be displayed in f format with two decimal digits.

Answer:
Hi Riahroo! This is a good question on the concept of relational databases.
We can normalize the relations as follows:
Flight
(flightnumber (unique), flighttime, airline_id, departure_city, arrival_city, passenger_id, pilot_id, airplane_id)
has_one_and_belongs_to :airline
has_many :passengers
has_one :pilot
Itinerary(passenger_id, flight_id)
Belongs_to
Passenger_details
(passengername (unique), gender, date_of_birth)
has_many :flights
Pilot
(pilotname (unique), gender, date_of_birth)
has_many :flights
airline(airlinename)
airplane(planeID, type, seats))
Explanation:
To normalize a relation, we have to remove any redundancies from the relationships between database objects/tables and simplify the structure. This also means simplifying many-to-many relationships. In this question, we see there is a many-to-many relationship between flights and passengers. To resolve this we can introduce a join table which simplifies this relationship to a one-to-many between the objects.
